Why is Dropbox taking up so much space on computer?

Recently, a number of users found that Dropbox would occupy a lot or even 100% of the hard disk space when running, which seriously affected the proper work of other programs and the computer. This situation will be improved after closing the Dropbox program.

What are the main reasons for Dropbox taking up too much disk space? Besides the fact that the normal run of Dropbox needs to occupy a reasonable quota of space for synchronizing files, we found that the following causes can lead to Dropbox disk usage 100%:

You are syncing large files or too many files.

There are third-party apps or other external factors that conflict with Dropbox.

Dropbox is not running in the right place, e.g. you are running Dropbox and keeping the Dropbox folder on a NAS device.

The file access for Dropbox is not set correctly.

After understanding the reasons that cause the Dropbox 100% disk usage issue, in addition to closing third-party apps that conflict with Dropbox, running Dropbox on a hard disk on your computer, and configuring the correct permissions for files, you can do the following four ways to free up hard disk space.

4 ways to fix Dropbox high disk usage on computer

Typically, the main reason for Dropbox using too much memory on Mac or Windows is that there are too many files in the Dropbox folder and you keep all of them locally available. The following 4 methods can help to work you out.

It should be noted that if you need to keep every file in the Dropbox folder available locally, it will definitely take up space on your hard disk, whether you are a free or paid Dropbox user.

Solution 1. Remove large files from your disk

If you are in a no-network situation and need to keep all your files locally accessible, one of the solutions to Dropbox taking up space on your disk is to delete the large and useless files on your hard drive. You can also make room on your hard drive by partially deleting unneeded Dropbox files.

Solution 2. Selectively sync files to your hard disk

By default, Dropbox automatically syncs all cloud files to the Dropbox folder on your computer. How can you free up hard drive space in the event of not deleting Dropbox files or local files? Dropbox offers a selective sync feature that is available to all Dropbox users. It works by allowing users to remove specific Dropbox folders from the hard drive to save space.

You can refer to the step-by-step guide below we illustrate on Windows to turn on selective sync on Dropbox:

1. Run Dropbox on your computer and click the Dropbox icon on the taskbar. Then, tap the Settings button and select Preferences.

Dropbox Preferences

2. In the Sync section, click Selective Sync.

3. Uncheck the folders that need to be removed from your hard drive. Then, tap Update.

But, please note that selective sync only supports removing folders, not individual files locally.

Solution 3. Use Smart Sync

Smart Sync on Dropbox is designed to help users solve the Dropbox using too much disk space problem by making online-only files, thus freeing up space on the computer hard drive. Setting individual files online-only is available on Smart Sync and it provides automatic smart sync.

However, Smart Sync is only accessible to Dropbox advanced plan subscribers. If you are a free Dropbox plan user, please turn to other methods to solve the Dropbox high disk usage problem. To set a single file or a whole folder online-only, here's how to do:

1. Go to the Dropbox folder on File Explorer (Windows) or Finder (Mac).

2. Right-click the file or folder you want to make it online-only, click Smart Sync, and choose Online-only.

Windows Smart sync

You can turn on Dropbox automatic smart sync with the steps below:

1. Tap on the Dropbox icon, click Settings, and then Preferences.

2. Press On under Save hard drive space automatically in the Sync tab.
